MASSACHUSETTS.

HAIR-PIN Specification of Letters Patent.

CUTTER.

Patented June 11, 1907.

Application filed May 15,1906. Serial No. 317,039.

To all whom it may concern:

Be it known that we, WARREN H. Goon- ALE and ALsToN L. PRESTON, both of Leominster, in the county of WVorcester and State of Massachusetts, have invented certain new and useful Improvements in Hair- Pin Cutters; and we do hereby declare that the following is a full, clear, and exact descri tion of the same.

,T 's invention has relation to improvements in dies for stamping or cutting out hairpins from sheet material.

It is an object of the invention to provide a novel device of this character which when brought down upon the material to be cut, such as celluloid, horn, hoof, or the like, of which flexible combs and hairpins are made, the knives will cut duplicate pins.

' It is a further object of this invention to provide a novel device of this character, whichwill be simple and efficient in operation.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings, forming part of this specification wherein like characters denote correspondin parts in the several views, in which i ure 1, represents a bottom View or cutting ace of the die. Fig. 2, is a longitudinal section of the die.

In the drawings 2, denotes the base of the die which is provided with the perforations 3, by means of which it may be secured to an operating plunger or lever.

Permanently secured to the under side of the base 2, is arranged a nest of knives 4, 5, and 6, having their cutting edges flush one with the other and suitably separated by the spaces 7, 8, and 9. In other words, the members of the cutters 5 & 6, intermesh. The blades are shaped to give the required curvature to the pins and are so arranged that the pins are cut in reverse relation. The outer knife 4, is so shaped as to give the outer contour of two pins extending one within the other, while the knives 5, and 6, are arranged sigmoidally and are positioned within the knife 4. Thus it. can be seen that in operation that when a blank is trimmed by the knife 4, and has the core cut out by the knives 5, and 6, that two formed pins are presented, it being only necessary to make a complete article to grind and polish the pins.

Although the invention has been shown,

and described as a single die, it is obvious that one die may be employed with the knife 4, while a second die could be employed with the knives 5 and 6, but as such an expedient is thought to reside within the scope of mechanical skill only, an illustration thereof is believed unnecessary.

Having fully described my invention what I claim as new and desire to secure by Letters Patent, is

1. In combination, a base, an outer cutter carried thereby, and nested cutters arranged within the outer cutter, the interior or nested cutters being sigmoidal in form, the members of the sigmoidal cutters intermeshing.

2. In combination, a base, an outer cutter carried thereby, and nested cutters arranged Within the outer cutter, said cutters having their blades separated one from the other each of said nested cutters being sigmoidal, the members of the sigmoidal cutters intermeshing.
